Study AreaStudy Area
• Approx. 1/3 mile long
• Two signals
• Three unsignalized intersections
• 30-35 mph posted speed
BackgroundBackground
• Selected as High Incidence Area based on pedestrian collision density
• 26 pedestrian collisions over 7 years (2004-2010)
• 73% of ped collisions resulted in injury or severe injury
• Heavy pedestrian activity related to land uses and public transportation
• Multi-lane Major Highway running through an densely developed, urban corridor
What is a Road Safety Audit?What is a Road Safety Audit?
A road safety audit is a
formal safety performance examination
of an existing or future road or intersection
by an independent audit team.
What is an RSA?What is an RSA?
An RSA is a tool that:• Is a formal process
• Focuses on safety issues
• Proactive review of observed and potential safety issues to reduce risk
• Considers various environmental conditions
• Considers all road users
RSA ProcessRSA Process
RSA team will conduct
Steps 3-6 over 2 day
session
Review relevant data
to include:
•Community input
•Maps/drawings
•Future plans
•Crash data
•Traffic volume (pedestrians and vehicles)
•Signal phasing and timing
4. Field Review4. Field Review
• Observe road user characteristics
• Observe surrounding land uses
• Observe link points to the adjacent transportation network
5. RSA Analysis5. RSA Analysis
• Workshop setting
• Review background reports and design criteria
• Systematically review drawings and other information/data
• Identify, prioritize, and mitigate safety issues
6(a). Preliminary Findings Discussion6(a). Preliminary Findings Discussion
• RSA team, design team, owner
• Discuss preliminary findings and possible solutions
• Use results to write RSA report
6(b). RSA Report6(b). RSA Report
• Documents the results of the RSA
• Identifies and prioritizes safety issues
• Includes suggestions for improvements
